Paddy Barnes made it two wins from two pro bouts with victory over Argentina's Adrian Dimas Garzon at the Waterfront in Belfast last night.
The three-time Irish Olympian, introduced as the "Belfast Leprechaun", took all six rounds in his home town in a convincing 60-54 verdict over the tattooed Mendoza bantam.
Barnes' impressed with superior footwork and shot selection in all six frames of a relatively tame affair against the durable journeyman in his first six-round bout.
"I got a good six rounds in there," said Barnes, who added that he will be at Madison Square Garden in New York on St Patrick's Day to support his former Irish team-mate Michael Conlan on his pro debut.
Jamie Conlan picked up the vacant WBC silver international super-flyweight title via a split decision against Yader Cardoza in Belfast.
Conlan was knocked down in round eight but he recovered well to extend his professional record to 19-0 at Waterfront Hall.
The 30-year-old, who remains on course for a world title eliminator, edged the first three rounds but Cardoza worked his way into the contest in round four.
The Nicaraguan then sent Conlan crashing to the canvas after a flurry of punches in round eight which rocked the Northern Irishman.
Conlan, though, composed himself well and, despite suffering a cut above his eye, held on to claim the victory.
Elsewhere on the Waterfront undercard, Belfast's Tyrone McKenna halted Jake Hanney to secure the vacant Celtic super-light title, McKenna enduring after suffering a nasty gash near his left eye in the first to stop the Dubliner in the sixth.
Meanwhile, aside from being slightly wobbled with a left in the first, Phil Sutcliffe Jnr dominated versus Miguel Aguilar, the Nicaraguan's corner throwing in the towel in the fourth with their man taking heavy punishment.
The Dubliner, son of two-time Irish Olympian Phil Sutcliffe, meets Josh Leather in Leeds in May for the vacant IBF Intercontinental title.
Meantime, Marco McCullough dropped Lionel Hernandez with a sweet right in the first en route to a 80-71 points win. The Belfast feather, rarely moving out of second gear, looked poised to score an inside-the-distance win in a one-sided eight-rounder, but Hernandez, to his credit, endured until the final bell.
Tipperary's Con Sheehan, with Peter Fury working his corner, extended his pro stats to five wins on a 80-72 points win over abject Hungarian heavyweight Ferenc Zsalek, who was ticked off by the ref for not throwing punches.
"He took some good shots, just like a punch bag," said Sheehan. "It's a learning curve.
"We're practising one thing at a time in the gym, we're getting there. Maybe I should have took him out."
